Additional Details

The UDZV16B features a Zener voltage (VZ) of 16V with a specified tolerance. The dynamic impedance (ZZT) is typically low to ensure stable voltage regulation. The maximum power dissipation (PD) is an important parameter to consider, as exceeding it can lead to diode failure. Refer to the manufacturer's datasheet for detailed specifications, including the operating temperature range, maximum surge current, and reverse leakage current.

When using the UDZV16B, a series resistor should be used to limit the current flowing through the diode, protecting it from overheating and potential damage. The value of the resistor should be chosen based on the input voltage and the desired Zener current.
